Cara Membuat Slideshow/Featured Content di blog

Kali ini, saya mau share sebuah cara untuk membuat slideshow. Slide ini menggunakan Jquery. Slideshow ini bisa kita gunakan untuk menampilkan gambar dan link ke produk/jasa/link yang menjadi "produk" dari web/blog kita.

Untuk melihat demo-nya, klik di sini.

Langsung saja :
1. Login ke blogger. Dashboard--> Design - -> Edit HTML.
2. Kemudian, cari kode </head>.
3. Copy kode di bawah ini dan paste SEBELUM kode </head>.

<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js' type='text/javascript'></script>

<script type='text/javascript'>
//<![CDATA[

$(document).ready(function() {

//Execute the slideShow, set 6 seconds for each images
slideShow(3000);

});

function slideShow(speed) {

//append a LI item to the UL list for displaying caption
$('ul.slideshow').append('<li id="slideshow-caption" class="caption"><div class="slideshow-caption-container"><h3></h3><p></p></div></li>');

//Set the opacity of all images to 0
$('ul.slideshow li').css({opacity: 0.0});

//Get the first image and display it (set it to full opacity)
$('ul.slideshow li:first').css({opacity: 1.0});

//Get the caption of the first image from REL attribute and display it
$('#slideshow-caption h3').html($('ul.slideshow a:first').find('img').attr('title'));
$('#slideshow-caption p').html($('ul.slideshow a:first').find('img').attr('alt'));

//Display the caption
$('#slideshow-caption').css({opacity: 0.7, bottom:0});

//Call the gallery function to run the slideshow
var timer = setInterval('gallery()',speed);

//pause the slideshow on mouse over
$('ul.slideshow').hover(
        function () {
                clearInterval(timer);
        },
        function () {
                timer = setInterval('gallery()',speed);
        }
);

}

function gallery() {

//if no IMGs have the show class, grab the first image
var current = ($('ul.slideshow li.show')?  $('ul.slideshow li.show') : $('#ul.slideshow li:first'));

//Get next image, if it reached the end of the slideshow, rotate it back to the first image
var next = ((current.next().length) ? ((current.next().attr('id') == 'slideshow-caption')? $('ul.slideshow li:first') :current.next()) : $('ul.slideshow li:first'));

//Get next image caption
var title = next.find('img').attr('title');
var desc = next.find('img').attr('alt');

//Set the fade in effect for the next image, show class has higher z-index
next.css({opacity: 0.0}).addClass('show').animate({opacity: 1.0}, 1000);

//Hide the caption first, and then set and display the caption
$('#slideshow-caption').animate({bottom:-70}, 300, function () {
                //Display the content
                $('#slideshow-caption h3').html(title);
                $('#slideshow-caption p').html(desc);
                $('#slideshow-caption').animate({bottom:0}, 500);
});

//Hide the current image
current.animate({opacity: 0.0}, 1000).removeClass('show');

}
